这段代码有几个语法错误，可能是复制粘贴的时候出错了。以下是修正后的代码：

import random

while True:
    player_choice = input("请选择：石头(R)、剪刀(S)、布(P)：").lower()
    
    while player_choice not in ['r', 's', 'p']:
        player_choice = input("选择无效，请重新选择：石头(R)、剪刀(S)、布(P)：").lower()
    
    computer_choice = random.choice(['r', 's', 'p'])
    
    if player_choice == computer_choice:
        print("平局！")
    elif (player_choice == 'r' and computer_choice == 's') or (player_choice == 's' and computer_choice == 'p') or (player_choice == 'p' and computer_choice == 'r'):
        print("你赢了！")
    else:
        print("你输了！")
        
    play_again = input("想再玩一次吗？(y/n)").lower()
    if play_again != 'y':
        break

需要注意的是，在 Python 中，代码的缩进非常重要。如果缩进不正确，就会出现语法错误。因此，建议在编写代码的时候注意缩进，尽量保持代码的整洁和可读性。
